The root cause is we didn't check if the optionalpath is valid or not, the registerbuildation function directly invoke the path var and cause the invalid memory error. We just return if the launcher doesn't exist. The ctx.VisitDirectDepsWithTag() also handles allowmissingdependency so we are ok if launcher doesn't exist.
